We gathered the second engine info from the eBay ad:

This guy started Greasel/Golden Fuel Systems, one of the first US grease-kit companies, so he has a bit of experience. I would think the split-tank alone is an interesting feature, even if one never runs grease. Might be nice for running 100% Biodiesel in cold weather, especially homemade stuff.
Hey, Dad, where are you located? I'm in Berlin, CT.
Hi
I'm in Worcester.
Yes the heated fuel lines would help running B100 in the New England winter huh?!?
I didn't know he had it on EBay so I didn't know about the engine, my apologies. Here is perhaps a further explanation of what could have happened to the oem engine besides just "lack of maintenance":
Here is the scernio I have heard happens when running "cold" wvo in a "cold" (not up to temp) engine. Fuel does blow-by and wvo in the crankcase is a very bad thing. If you switch over to wvo too early there is more of a chance that there will be wvo in the crankcase.
From Chris Goodwin at the Frybrid website:
Quote:
You have sufficient fuel temps and as long as the engine is at operating temp before switch to VO I would be satisfied. The issue of early switch is this: Let us assume that you have a tank filled with 160-180F oil and you start the motor and switch right to VO. If you look at the function of the engine you will see that diesels bypass quite a bit of fuel past the rings until they reach operating temp, when the engine has heated up and the pistons and rings expanded enough to seal properly, they bypass very little. If the fuel bypassing the rings is VO you will end up with polymerized oil in the crankcase which will burn the bearings out of the motor. Larger diesels do this so badly that professional drivers and captains start and run the motor under load, but not full load until warm, then come on the power hard to clear the system out and seal the rings. Bus drivers will fire up a motor, let it run at fast idle until the air system is up, then they warm it and hit a hill at full throttle before picking up any passengers just to get the power up and the rings sealed. While this means little in smaller engines it does accurately represent the bypass of fuel into the oil. Check out the blowby on your engine cold by removing the oil fill with the engine running, then do it again after a good loaded run.

So, I am not saying that this was the cause, I just have read an opinion from an expert in the field. Toward the bottom of the quote, notice what Chris also says about "small engines".
That is why while the tank(s) may be my own design, the wvo system will most likely be a Frybrid.
Just another 2-cents
